Recently, I’ve noticed my 4.0L engine over 2500rpm gives me some noise. It sounds like lifters are not properly adjusted, I mean the push rods and arms….
I’m running with 10W40 semi-synthetic brand new oil and pressure around 15 psi when idle and 45 psi when higher rpm. I’m supposing oil pressure is OK. Temperature always on 212°F.
Considering this engine has 60K miles, is that OK if I just adjust the push rods and arms ? Or do you recommend an extra attention to other components ?
I’ve seen some problems with lifters that just don’t “charge” them selves when I turn the engine on or when the loose their internal pressure when I turn the engine off….but in general I think this happens with higher mileage.
Any tips ?
Thanks.
